ENGINE VALVE ATTACHMENT.

Specification of Letters Patent.

Patented Apr. 6, 1920.

Application filed April 18, 1918. Serial No. 229,420.

specification.

This invention relates to improvements in valve attachments for internal combustion engines of the valve-in-head type and 1t 1s l'the principal object of the invention to provide an attachment for eliminating all lateral or side play of the rocker arms thereof,l

thus insuring proper functioning of the y same and the valve and also reducing noise to minimum during operation.

Other objects will be in part obvious and in part pointed ont hereinafter.

.In order thatv the invention and the manner of its application may be readily understood by those skilled in the art, I have in' the accompanying illustrative drawings and l in the detailed following description based vimproved play removing devices,

thereon set forth a the invention.

In the drawings:

Fi ure 1 is a fragmentary top plan showing tie improved attachment applied to the rocker arms of an engine of valve-in-head type, and

Fig. 2 is an /elevation of one of the novel devices.

Having more particular reference to the drawings, in connection with which like reference characters will refer to corresponding parts throughout the several views, E desigates a fragment of an internal combustion engine of the valve-in-head type, the same having bearing arms b arranged upon the heads of the various cylinders thereof between which rocker arms a are pivotalLy mounted; saidrocker arms, as will be understood, being adapted' for Iintermittent engagement' with the stems of the valve controlling the intake and exhaust ports of the preferred embodiment of engine cylinders and having connection with sultably timed operating Ymechanism, not shown. l

Engaged with the rocker arms ar. are my the same comprising hooked elements land 2 the inner ends of which are looped upon themselves and engaged with the adjacent ends of contractile coil springs 3. As clearlyshown in the Fig. 1, the hooked members 1 and 2 are engaged over the rocker arms a and in this way serve to prevent any lateral or side play or movement of the same, thus, insuring proper functioning of the rocker arms and the valves engaged thereby and further, reducing noise to minimum during the operation thereof. It will, however, be readily understood that the improved devices in no way interfere with the vertical movement of the various rocker arms a engaged thereby and as a consequence, the intermittent engagement of said rockerarms with the adjacent ends of the intake and exhaust valve stems can be efectually carried out.

I of course desire to have it understood that the improved devices or attachments may be made in different sizes and further, that the-hooked membersv 1 and 2 employed in connection therewith may be varied in design to allow their attachment to rocker arms differing in sizes and shapes. Furthermore, springs varying in tension may be employed, such as conditions or preference may dictate.

As above indicatedJ I do not wish to be understood as confining the invention to the particular embodiment chosen for illustration herein, nor to the exact construction, arrangement and adaption of parts shown and described, but I reserve the right to make any changes and alterations that fairly fall within the spirit and scope of the invention.

I claim: i l

1. In combination with the rocker arms of an internal combustion engine, means for yieldably interconnecting the same to prevent lateral or side movement thereof.

2. In-combination with the rocker arms of an internal combustion engine, of resilient means disposed transversely of the same and engaged therewith for preventing lateral or side movement of the same but permitting free vertical movement thereof.

3. In combination with the rocker arms-of an internal combustion engine, of hooked members engaged therewith, and contractile coil springsengaged with'the adjacent ends of said hooked members.

In testimony whereof, I aiix my signature hereto.

BENJAMIN H. KE'ssLER.
